Figure 1 is a side elevation of the device and Fig. 2 is a plan view of the same.

Corresponding letters refer to .correspending parts throughout the drawings and specification. As shown in Figal, AJis a car upon which mixer D, an operating platform D and hop )QIS d d are mounted. At tl-lllOOttOll'l oi said hoppers are doors a d" and in the top of the hoppers are inclined dumping chutes (Z (Z formed of bars spaced to let the aggregates passthrough. E is a supporting frame on said *car A and his a tower supporting sheaves f, f and f". .H is a winch drum. H and H are friction winding drums and 72. and k are friction brakes for controlling dru ns H andnH A winch l! drum (J a .lrame (x and track rope sheai es on c and c are niounted on car G. I is a track cable wound around a winch drum H, passed over sheave f through a carriage J anda sheave'housing K over a sheave 0 to coupling shackles l". I isa second cable forming a continuance of thecable I from shackles l and! connecting with xwinch drum C. I prefer to use the winch drums G and, Has a ready means of tightening the tnack cable l and its: continuation 1 but. any simple 'ilasteningat or near-the locationsof winch drums would suffice and be withinzthei spiritof my invention. K is a sheave in. housingli; and K is a connect-ion between housing K and theframe'C A. cable L wound around a drum Hfidhence passed over sheave f overthe sheave 3' in the car-- r go J, thence under sheave N in housing; ll on the bucket M, over the sheave j in. the carriage J, thence over sheave K in housing K and'thence hack and fastened to the housing N on the bucket M. That drum H and. allowing cable .L'to

tion of cable L which: reaches betweensheave K and housing)? may be regarded-as a tail rope to draw lbucltet'M and carriageJ in opposite directionto acable O; and While l prefer to fasten the end of therrope to the housing N it maybe fastened to carriage J,

or to the bucket M, and produce like results and be within the-spirit oi myinvention; Said cable 0 isrliastened to drum H, passed thence over the sheave f and thence fastoned to the front of bucket M. The track carriage J runs on the track cable I and is composed of shell 9', the track sheaves 'j and theibluclret carrying sheaves jend j. The bucket M is a rectangular-box open at its front end and having a lip' m bentslightly downwardv and sharpened to form a cutting edge. thehousi'n N which is fastened to the top of the bucket M, preferably near the fronl.

The sheave N :is carried in end. The concrete mixer .Dmay beef-any standard type and arranged to receive the material from the-hoppers d d and discharge the concrete into any suitable. conveyor, not shown.

To handle my device machinery car A I and a number of cars B \B, comprised preferably of a cement car, severalarock and sand cars and the box-car C, are run upon a side track near where concrete retaining Walls for track elevation.or for other similarpurposes are to be erected, and the machinery set in motion. The eableway 0peraitesas follows: If the operatorholds the drum H with the brake h and releases drum H theweight, of bucket M: in the loop of cable T) will cause said cable L to unwind from drum H and pass over the several sheaves and'thebucket will-fall to the position shownin the dottedlines over cars B 13. inFig. l; by then pulling in on cable 0 on ay out thebucket and, carriage will move orward and fill the bucket, and after filling holding the cable L and pulling on the cable 0 will raise and advance the bucket simultaneously, and after the bucket is raised sufiiciently the paying out of the cableL and hauling in onthe'cable Oat equal. speed will hold the bucket at a given height and advance it toward the point of dumping and a reversal of the latter motions will send the bucket backward ands quieker nayin vout Qf'theI cable-Q then the. cable L will si ultaneously' flected sidewise to miss the material cars B vious string of cars the difference of length may be moved on a direct line from the point of fill ,to the point of dumping or the reverse. It will be further noted that the paying out of either of the cables L or O, singly or simultaneously, will drop the bucket M and the winding of the same either singly or simultaneously will raise the bucket. The bucket on being brought to the hopper for which it is intended is allowed to drop and empty on the inclined chute within the hopper after which it may be returned and refilled. The men attending to the mixer dump the material from the hop pers into the measuring hopper on the mixer, not here developed, and the process proceeds until the material cars are empty. Then the bucket M is allowed to remain in one of the hoppers and the carriage J is allowed to fall and rest on the bucket M as the cable I is payed out from the winch C. the connection K having first been loosened all the cables and the sheave and housing at- K and K are lowered to the ground and de- B The shackles I" are then separated and the slack of the cable I thrown on the car C after which the car C and the material cars are switched out and other material cars and car C are again switched back in the same order as before and the shackles I connected and the cables and sheave again hoisted to position and the operation re pcated ml infinitmn.

Should the new string of material cars for any reason be longer or shorter than the preof the cable I between sheaves f and 0 are compensated for by paying off or winding on cable on the winch H.

In the building of concrete retaining walls for railway track elevation it becomes necessary at times to conform to the curvature of the track and it will be readily seen that if the device illustrated be placed on a curve the cars A, B and C will conform to the curvature, but the carriage J and the bucket M will move in a direct line and in dropping the bucket M into thecars it must be defiected 'sidewise toward the outside of the curve. To partially compensate for the above the she: yes sand 0 are provided on the frame C Normally, the track cable I passes over sheave 0, but under the conditions mentioned above it turns over one of the sheaves c or 0 The conveying and mixing machinery may be operated by any suitable power, singly or collectively, by individual electric motors from a central plant, or by individual gas engines. but preferably collectively by a steam plant, not herein shown.

tice the frame C on The present method of procedure is to have a car containing mixing machinery on a track and on the same track a train. of aggregates, viz: sand, gravel, stone and cement in cars; upon the said cars plank staging and wheelbarrows are placed. Laborers shovel and wheel the aggregates to the mixer at great expense because to avoid switching cost and delay (tiring working hours some of the aggregates have to be wheeled from cars quite distant from the concrete mixer.

Many cable conveying devices have been designed for various purposes, and they chiefly comprise two or three classes, viz., those that are merely conveyors, those that convey a grab bucket and those as illustrated in Bennett, 895,064. The latter class are of necessity only suited to short range work, by reason of the necessity of proportioning the height of mast to the distance the bucket must travel on the track rope by gravity to reach the extremity of operation.

It will be noted in Bennett by reference to Fig. 5 that he uses his track rope as the mediumof raising and lowering his bucket and that in doing so, he uses or wastes a lot of power in partially straightening his cable F under load. In my invention it will be noted that the track cable is brought under tension while unweighted and the tension maintained until a new supply of aggregate is required. It will be further noted the bucket is supported on the carrier by a loop in the cable and the pull onsaid cable O is reduced to less than half of the weight of the bucket and its load. It will be further noted that the forward and backward motion is positive and the possible range of operation thereby largely increased. In praccar C is made low, as shown, so that in switching in a new supply of aggregates car Cwill pass under overhead structures such as trafiic and semaphore bridges. but if desired the frame on car C can be made even higher than the frame on car A.
